will reach a maximum when all available enzyme effectively exists in the form of the E  S complex. This situation occurs at high substrate concentrations, where the enzyme is said to be saturated with substrate. If enzyme concentration is held constant, a plot of initial reaction rate against initial substrate concentration (Fig. 2.6) will yield a curve typical of saturation kinetics, where a plateau is observed at high [S]. The plot shown in Figure 2.6 has two regions that are important in analytical methods. First, when [S] is very low, the reaction rate is linearly related to [S]; under these conditions of rst-order kinetics, reaction rates can be used to quantitate substrate. The second region of interest occurs at very high [S], where the reaction

rate is independent of [S]; under these conditions of zero-order kinetics, all of the available enzyme exists as E  S, and the reaction rate can be used to determine the total amount of enzyme present in the sample. 2.5.1. Simple One-Substrate Enzyme Kinetics One-substrate enzyme kinetics are applied to many reactions that require water as a cosubstrate, that is, the hydrolases (such as esterases and proteases), since aqueous solutions have a water concentration of 55.6 M. The kinetic model is based on the initial formation of the enzyme substrate complex, with the rate constants as shown in Eq. 2.11. E S $ ES ! E P

From this model, the dissociation constant of the enzyme substrate complex, Kd , will be equal to k 1 =k1 , which is equal to [E][S]/[E  S]. The mathematical derivation of the expression for the reaction rate is based upon the initial rate of the reaction. We will assume that, almost immediately after the reaction begins, the rate of change of concentration of the enzyme substrate complex is zero; that is, a steady-state [E  S] value is achieved. The rate of change of [E  S] with time, d[E  S]/dt, may be expressed as in Eq. 2.12: d E  S =dt k1 E S k 1 E  S k2 E  S 0 2:12

where [E  S] is formed only from the association reaction, but is removed either by dissociation into E and S, or by conversion to product. The enzyme exists in solution as either E or E  S, so that at any time, the total enzyme concentration is equal to the sum of these concentrations, or [E]0 [E] [E  S]. Using this expression to substitute for [E] in Eq. 2.12 yields d E  S =dt k1 E 0 E  S S k 1 E  S k2 E  S 0 Rearranging to collect terms in [E  S] yields Eqs. 2.14 and 2.15: k1 E 0 S k1 S k 1 k2 E  S 0 E  S E 0 S =f S k 1 k2 =k1 g 2:14 2:15 2:13
